Introduction

The Delhi Sultanate (1206–1526 CE) marked the beginning of Indo-Islamic rule in India. Established by Turkish and Afghan rulers, it laid the foundation for administrative centralization, Indo-Islamic cultural synthesis, and the use of Persian as a language of administration. The period is divided into five ruling dynasties that governed from Delhi and shaped India’s medieval history.
